Pump stations play a critical role in keeping communities safe from flooding during storms. This is particularly true of those situated near coasts, rivers, and lakes. Bar screens and trashrakes are commonly employed to protect these pumps, but not just any screen will work in these scenarios. With this in mind, Duperon has developed its… Continue reading
In wastewater operations, washer compactors perform a deceptively simple function: reducing debris volume for handling and disposal. But a lot of factors can complicate this process, including atypical wastewater debris, inconsistent debris volumes, and solids that cling to and/or jam the auger.

The adage about the three most important factors in real estate value — location, location, location — carries a certain degree of truth for wastewater collection systems as well. How close to the source of problematic clogging materials a debris handling solution is installed can be just as important as how efficiently that solution neutralizes… Continue reading
Most bar screen and raking systems are expected to last 10 to 25 years before needing replacement. As components wear, and steel corrodes, wastewater treatment plants (WWTPs) have to choose between replacing parts and specifying a new system. Both situations can present a serious challenge. For example, replacing parts may seem more cost-effective in the… Continue reading
Effective wastewater screening during normal flow looks very different from screening during peak flow events. Under most circumstances, however, it isn’t possible to address both effectively. As such, engineers and municipalities design their screening with peak flow in mind. This means debris bypass or larger screen opening sizes and slower scraper speeds, a compromise that… Continue reading
Keeping loose vegetation out of a waterway is a common purpose for nearly every trashrack. As vegetation accumulates on a screen, it can cause blinding and lead to head loss. In applications with heavy vegetation, large floating mats can be particularly problematic. There are a lot of trashrack designs that have capabilities to address vegetation,… Continue reading
Trashracks serve the simple but critical purpose of keeping large debris out of a water system. They are often placed in high-volume channels, drainage canals, pump stations, or flood control systems. Whether the goal is to pull water out of a residential area or supply water to a hydroelectric plant or a nuclear facility, it… Continue reading
Many wastewater treatment plants (WWTPs) design their screening with peak flow in mind. This means debris bypass or larger screen-opening sizes and slower scraper speeds, a compromise that results in suboptimal screening during normal flows. Unfortunately, letting more debris through the screen during normal flow can lead to costly problems, such as pump clogs and… Continue reading
Most bar screen and raking systems are expected to last 10 to 25 years before needing replacement. As components wear, and steel corrodes, wastewater treatment plants (WWTPs) have to choose between replacing parts and specifying a new system. However, Duperon customers have a third option that can save the money and downtime of buying a… Continue reading
